too bad u bought too much, but some times it can happen to the best of us.
my suggestions are: 1-Try contacting a Salvage Store in your area or if any good one online who can take them off your hands.
2- Try to donate them to a Charitable Organisation for them the refix them to sell them like good will who sells them to help the community.
3-Any Electronics dealers who can reuse them for parts etc.
when u donate do a well established Charitable Organisation u can get a reciept for a tax deduction all depends where u live and how the system in your
area is set up. these are very good tips for u and i really hope u found a solution.
P,s...Remember to think before u leap! especially when its about your heard earn money,budget your self.Most of all make sure u have a targeted audience for such a product first.Not always but it sure helps. take care. :
